2001, finished components were delivered to General Motors in the USA. As the workshop at the former location in Ditzingen became too small, Spiess Tuning moved to a specially designed new building in 2001. In the new 2,400 sqm halls, the four new test benches (three static, one dynamic) formed important elements for the ongoing success in racing. The new location is still the headquarters of Siegfried Spiess GmbH at Dieselstraße 11 in Ditzingen. Spiess also achieved great successes in the ATS Cup, the German Formula 3 Championship. Until 2008, all championship titles were won by Opel-Spiess for five consecutive years. In Argentina, 4-cylinder Opel engines modified by Spiess were used in touring cars in 2003. In addition, in both 2003 and 2004, Ryan Briscoe, Nicolas Lapierre and Nico Rosberg were able to perform confidently with the Opel-Spiess engine in the Formula 3 Euroseries, the world's highest Formula 3 championship at that time. In 2004, Karl Reindler won first place in the Australian Formula 3 Championship with the Opel-Spiess engine. In the same year, Siegried Spiess GmbH extended its business activities to prototyping and testing of high-performance derivatives. Spiess pushed the cooperation with VW and entered the Dakar Rally. In cooperation with VW, the first diesel engine for long-distance rally events was developed and manufactured by Spiess. In 2006, the team narrowly missed out on victory, which was followed by the Central Europe Rally in 2008. The first Dakar championship title for VW and Spiess followed in 2009 with Giniel de Villiers and Dirk von Zitzewitz at the wheel. In both 2009 and 2010, Spiess and VW achieved the sensational triple win, after which VW decided to end its participation in the Dakar Rally. Volkswagen returned to the Formula 3 stage in 2007 as an engine supplier. Initial testing in September was followed by continuous racing in 2008 and already the first victory. Spiess Power dominated the ATS Cup for six consecutive years. In 2014, Tom Blomqvist and Max Verstappen finished second and third in the European Formula 3 Championship with Spiess-VW. Further championships in the European Formula 3 Racing Series followed in 2015, 2017 and 2018. In 2016, he entered the Superformula Lights in Japan after Formula 3 changed the regulations. In 2017, Mitsunori Takaboshi won the championship there. At the Macau Grand Prix, Dan Ticktum finished first with a VW Spiess engine. In the European Formula 3 Championship,
